Voltage Control and Protection

The IC UC3854, what it does is, it helps in active power factor correction, right? Now normally, if we don’t correct the power factor, then power system will pull current from the AC mains in a way that’s not a nice sine wave but rather distorted. This IC takes care of all the control stuff […]

This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]

When we talk about hot-swap controllers, it is basically an electronic device or integrated circuit (IC) that allows you to the insert or/and remove circuit boards, modules or parts within an active system without having you to switch off the system. It regulates the surge current whenever a component is installed and protects from short […]

In this post I have explained a few very simple boost converter circuits using only BJTs, or transistors. Let’s learn more. What is a Boost Converter A DC boost converter circuit is designed for stepping-up or boosting a small input voltage levels to a desired higher output voltage level, hence the name “boost” converter. Since […]

In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]

This simple mains 220 V, 110 V AC voltage home protector circuit will protect all the mains operated appliances of your home from high and low voltage situations and also from sudden voltage surge. The circuit can be used with 220 V AC inputs and also with 110 V AC inputs. The circuit will basically […]
